Amsterdam Airport Schiphol (Dutch: Luchthaven Schiphol, Dutch pronunciation: [ˈlʏxtˌɦaːvə(n) ˌsxɪpˈɦɔl]) (IATA: AMS, ICAO: EHAM) is the main international airport of the Netherlands, located 9 kilometres (5.6 mi) southwest of Amsterdam, in the municipality of Haarlemmermeer, province of North Holland. It is the third busiest airport in Europe in terms of passengers. The airport is built as a single-terminal concept: one large terminal split into three large departure halls. Schiphol is the hub for KLM and its regional affiliate KLM Cityhopper as well as for Corendon Dutch Airlines, Martinair, Transavia and TUI fly Netherlands. The airport also serves as a European hub for Delta Air Lines and Jet Airways and as a base for EasyJet and Vueling. Schiphol opened on 16 September 1916 as a military airbase. The end of the First World War also saw the beginning of civilian use of Schiphol Airport and the airport eventually lost its military role completely. By 1940, Schiphol had four asphalt runways at 45-degree angles. The airport was captured by the German military that same year and renamed Fliegerhorst Schiphol. The airport was destroyed through bombing but at the end of the war the airfield was restored quickly. In 1949, it was decided that Schiphol was to become the primary airport of the Netherlands. The airport's official English name, Amsterdam Airport Schiphol, reflects the original Dutch word order (Luchthaven Schiphol).
